Design and Fabrication of Blood Drawing Device
This paper proposed a novel device to draw blood from the finger. PDMS is used as an actuated pump, the device has an advantage in a precise controlled the volume of blood drawn. The operation process of the blood drawing device with the deflection of the PDMS membrane is to generate negative pressure. For measuring the performance of the device, we also fabricate a PDMS tank as pig’s skin. Two different viscosity fluid are used, the red ink and pig’s blood. The result of red ink drawn is 0.2cc, and the pig’s blood is 0.1cc.
